to scream past our targets of renewable energy and be at 50% renewable energy by 2020 or 2022. we may be at 66%. it's coming. there were days this summer when germany generated more than half the power it used from solar panels within its borders. this is germany. munich's north of montreal. they don't have texas, california, nevada, arizona. >> the biggest immediate battle which is not getting the attention it should, in fact, it's getting very little attention is part of this whole fiscal mess coming up is the existing tax credits for renewables expire. and you see republican senators saying above all else, don't renew them. >> i think that position though, congressman, it has to break. you see more and more republican governors from red states. >> we have to insist on that. that's the most immediate thing. >> one big question i think is when you get on a path, if there's going to be a sort of virtuous cycle that can be kicked in with renewables in which things start to beat their expectations and i want to hear about what that future might look like after this break.
